Research design and methods: Twenty-nine people with T1D (PwD) who started to use MiniMed 780G (TM) participated in the study. Participants' 3-day food diaries and glycemic outcomes were analyzed at baseline and after (the 3(rd) and 6(th) month) switching to an advanced hybrid closed-loop system (a-HCL). Results: Mean carbohydrate, protein, and fat intake (energy %) at baseline were 49.1 +/- 4.5, 17.8 +/- 2.3, and 33.0 +/- 3.9, respectively, and there were no statistically significant differences during the follow-up period. However, low fiber (<14 g/1000 kcal) and high saturated fat (>10 energy %) intake in PwD, both baseline and follow-up period. The median auto-correction bolus ratio was 14.0 (9.5)% at auto mode after 14 days, 18.0 (11.0)% at the 3(rd) month, and 19.0 (7.5)% at the 6(th) month (p < 0.05). A negative correlation was present between auto-correction boluses with TIR in both the 3(rd) (r:-0.747, p < 0.01) and 6(th) month (r:-0.395, p < 0.05). A negative correlation was present between auto-correction boluses with TIR in both the 3(rd) (r:-0.747, p < 0.01) and 6(th) month (r:-0.395, p < 0.05). Conclusions: a-HCLS systems offer better glycemic control. Using the Minimed 780 G (TM) insulin pump system didn't change the energy and nutrient intake of PwD. This real-world follow-up study suggests that children, adolescents, and young adults with T1D consume saturated fat above and fiber intake lower than recommendations independent of the use of a-HCLS.
